General Mach Discussion / Re: How do you Resume Cutting?

« on: December 18, 2012, 01:09:45 PM »

That should have been one OR the other. A LOT of commercial machines have absolute encoders that as long as the batteries are good you don't loose position on reset.

With MAch3 when you reset Mach dumps everything in the buffer and looses all reference to position.  AND the machine may MOVE when the drives are turned off.

YOUR choice, your part, your machine

To resume after an Estop you would

Re Reference the machine

Reset the Origin (Xo Y0 Z0)of the part to be machined

Use Set Next Line to move to the line of the gcode program where you would like to restart at OR move to the line position in the Gcode screen

Use Run From Here to restart your Gcode program, Follow the prompts to restart.

Hope that helps, (;-) TP

Been sewing since I was 6. Mark or measure the inseam and send them on down.

The first BLUEPRINTS I learned to read were patterns (;-) sitting with mom while she made cloths.

Around this house EVERYBODY learns to Use Acad and Sew and COOK (;-) You got your laundry to do when you turned 10.


WELL the wizard only converts Mach3 to do cylindrical machining on a cylinder mounted in the fourth using XYZ axis Gcode. If you can CAM what you want laying it out in 2.5d or 3d cam then it should cut it. 

My main purpose for working it out is so we can do Plasma cutting on PIPE/Tubing WITHOUT having to have a 4th axis CAM to work it out then fight with A axis feedrates with plasma where the A would have to HAUL THE MAIL which most don't. You cannot just SLOW down the feedrate with plasma when you want to the machine HAS to be able to maintain Feedrate to maintain the arc height.

With the M107 the feedrate is controlled as a normal XY function so there is NO radius correction needed.

OK It seems ONLY the Param3() is broken. I can make it limp along like a 3 legged dog with PQ and have at least some error checking

M107 P## Q##

P set up the diameter of the material
Q sets the function mode of the Mcode
     1    = Turn OFF the M107 and return to standard mach3
     99  = Setup the M107 Mcode , Config
     911 = Emergency Restore the system to ORIGINAL Standard

OOPS TIME is UP, BACK to Sewing with the Granddaughter (;-)

FAQs / Re: Virtual Aixs

« on: December 17, 2012, 03:22:09 PM »

Ken I am not sure what you mean by virtual axis BUT you can bring the encoder into MACH3 and display the actual measure of motion. You can then compare the 2 values , Mach3 axis and encoder motion value.

SO I F the material slips on your conveyor where are you going to attach the encoder ? To the material

OK BIG GLITCH in creating a proper Mcode that is GOOF proof.  The param1() (also 2&3) values do NOT return to NIL after use AND I cannot find a way to clear them before closing the macro.

This prevents ANY conditional ERROR checking on the values as they are ALWAYS the same as the last use EVEN thought you never called this time ??

Does anyone know of a way to clear the Param1() Param2() Param3() values back to NIL or even 0 ?

Bummer , I can still make it work for me BUT that precludes and error checking and disaster recovery pretty much goes out the window except by doing it manually. NOT for the masses I am afraid.

OH well , That is usually the way it goes, CLOSE but NO CIGAR. AT least we have the Wizard.

As and option most VFD have a removeable display /programming panel. With a simple extention cable you can move it over to your control display. I did mine that way years ago in lue of fiddling with modbus/rs485/rs232

Just a thought, (;-) TP

TP is a Grandpa X 6

SO now what do we call this THING, hopefully something snappy.

OK NOW what do I do for something to do?  I was thinking about dragging out the old Cruise control for Mill to slow DOWN the FRO when the spindle speeds drops below a set point ans see IF it could be made better.  OR?

DOes anyone know of any BIG BOY toys that the NEW CNC VMC's can do that we need?

We also have this available from a MCODE

M107 P## Q## R##       (  P sets Part Diameter and Q sets teh Rotary Vel and R sets the Rotary Vel) OR we can set teh variables Q R with a #parameter call to update. 

 #570=100 (Vel)
#571=50 (Accel)

Then all you have for the Mcode would be

M107 P##     where the P is the part diameter

M108 would reset to standard.

OK I moved the rotary axis Velocity and Acceleration settings OUT to screen so you can mod them as needed.

The steps per are auto calculated now and should be correct for proper size based on part diameter.
